I don't know about a keyboard command, but I just played around a bit,
and the following code seems to work:

--8<---------------cut here---------------start------------->8---
(mapc (lambda (key)
	(define-key isearch-mode-map key 'isearch-printing-char))
      '([(adiaeresis)] [(odiaeresis)] [(udiaeresis)] [(ssharp)]
	[(Adiaeresis)] [(Odiaeresis)] [(Udiaeresis)] [(section)]))
--8<---------------cut here---------------end--------------->8---

The problem seems to be that non-ASCII characters are not classified as
"printing" when using isearch in Gnus (even though it works in other
modes).  Note that you may still not find all occurrences of a certain
character in the summary buffer; this is likely caused by encoding
differences (Latin 1 vs. Latin 9, etc.).
